Hello jspitz65, I don't know to much about Dashlane but this guide by Dashlane may help: https://support.dashlane.com/hc/en-us/articles/202699011-How-to-check-your-Dashlane-extension-in-Firefox Tell me if that Helped and Stay Safe!

Thanks, Tommy.

Image 1 is what I'm hoping to find when I search extensions. But, image 2 is what I actually see when I search for the extension. So, I'm still unable to resolve the problem.

Cheers!

Mozilla changed the Extensions scheme recently and now "side-loaded" extensions for Firefox disappear with an update; that affects Firefox extensions which were installed by a 3rd party application like Dashlane apparently did. Those 3rd party apps need to update or change something to get their app to work with Firefox and the new requirements; OR provide their extension for download / installation on the official add-ons website (I think).

Sorry, I don't keep with 3rd party apps like that. I don't use them and don't follow the changes that affect them.

Glad your happy, jspitz65!

Stay Safe!
